Spectrum sensing in a large-scale heterogeneous network is very challenging as it usually
requires a large number of static secondary users (SUs) to obtain the global spectrum states …

This paper discusses the fundamental principles of a cognitive-radio RF system. The key
points required to achieve a true cognitive-radio device are outlined. The operation of a …

Multisensor Data Fusion: From Algorithms and Architectural Design to Applications covers
the contemporary theory and practice of multisensor data fusion, from fundamental concepts …

Collaborative spectrum sensing in cognitive radio networks has been proposed as an
efficient way to improve the performance of primary users detection. In collaborative …

Cognitive radio networks need to continuously monitor spectrum to detect the presence of
the licensed users. In this paper, we have exploited spatial diversity in multiuser networks to …

In this paper, we propose an opportunistic spectrum sharing protocol that exploits the
situation when the primary system is incapable of supporting its target transmission rate …

The cognitive radio (CR) paradigm for designing next‐generation wireless communications
systems is becoming increasingly popular, and different aspects of it are being implemented …

Unlicensed secondary users (SUs) in cognitive radio networks are subject to an inherent
tradeoff between spectrum sensing and spectrum access. Although each SU has an …

This paper proposes efficient cooperative cyclostationary spectrum sensing schemes in
which each secondary-user (SU) performs single-cycle (SC) cyclostationary detection for …

Cognitive radio (CR) is a critical technology for improving spectrum utilization and solving
the radio spectrum scarcity problem. In CR devices, spectrum sensing is important to …
